Garbage Fees
Ever look through your phone bill and wonder what all the various fees are? You may see service fees, application fees, overage fees, etc.
While it seems like the additional fees should be added into the cost of having a phone, they aren't. These random fees seem like garbage to you, as they probably should...however, they help the phone company pay its overhead costs in running the business and bring new product to life (think: better cell connectivity, if nothing else).
